He suggests the widespread adoption of low-carbon alternatives that can “revolutionise the way we construct our schools and other vital structures.” Says Sheridan: “If these school buildings were originally designed for a 30-year lifespan, it was unrealistic to expect them to last 50 years without issues. If lessons are to be learned we must be mindful of these factors during future design phases and avoid overstretching the longevity of our structures.” He adds: “Another factor to consider as we contemplate rebuilding these educational institutions, is a pressing environmental concern – embodied carbon. The concrete originally used in these structures, and the replacement materials chosen, play a pivotal role in determining their environmental footprints and this is where products such as Alkali-Activated Cementitious Materials (AACMs) can make a huge difference.” Sheridan’s company, Cemfree, says that school designers can cut a school’s carbon footprint by upto 85% compared to Portland Cement by using AACMs and still maintain the integrity of concrete. Says Sheridan: “The situation with schools in England serves as a pivotal moment, highlighting the importance of responsible design, sustainability, and material selection in construction projects. It offers us a choice – to rebuild with materials that are both resilient and environmentally conscious or continue to use very carbon intensive materials. Could this be the catalyst for a transformation in our commitment to constructing safer, greener, and more sustainable educational spaces for generations to come?”
